"Revolutionary Privacy Solution: Cryptographers Unveil Total Search Privacy Approach"
Originally Published 2 years ago — by Quanta Magazine
Cryptographers have developed a secure method for preprocessing a single-server database, allowing for private information retrieval. The method involves transforming the information in the database into a mathematical expression that can be evaluated by the server. By using this approach, the authors were able to construct a new scheme that improves the efficiency of internet searches and programs requiring quick access to data. While the current implementation is not practically useful, further optimization could make private lookups from large databases a reality, offering hope for total search privacy.
